ANTICREE?ER FOR RAILROAD-RAILS.

Specification of Letters Patent.

Patented Apr. 25, 1916.

Application filed October 1, 1915. Serial No. 53,501.

T 0 all whom it may canoe-m Be it known that 1, DAVID F. VAUGHAN, acitizen of the United States, residing at Rivcrton, in the county ofBurlington and State of New Jersey, have invented certain new and usefulImprovements in Anticreepers for Railroad-Rails, of which the followingis a specification.

invention relates to improvements in anticreepers for railroad rails,which are adapted to grip the rails and engage a sta tionary part of theroad bed and prevent the forward, longitudinal displacement or thecreeping of the rails.

The object of my invention is to m an anticrccpcr of novel, simple,inexpei'isi e and otlicicnt construction adapted to g a rail base, andheld in gripping engagement with the raii base and in constant readinessfor action under all conditions by the ac tion of a table springassociated with the parts of the antierecper and the rail in a novcimanner to effect the desired result.

Witi'i this object in view the invention consists of the elements andthe combina tions of their. hereinafter fully described and claimed.

In the accouuianying drawings, illustrating my invention: Figure 1 is aplan view of a portion of a railroad rail, a portion of a cross-tiesupporting the sonic and-my improved anticrccper applied to the rail;'Fig. 2 is a side elevation of the parts shown in Fig. 1. Fig. 3 is atransverse section through the rail, on line 33 of Fig. 2. Fig. 4- is atransverse section through the rail and the anticroepor, on line 4-4 ofFig. 2. Fig. 5 is a perspective view of the spring.

Referring to the drawings, 2 designates a portion of a railroadcross-tie and 5 a railroad rail of usual construction. The cross-tic 2forms a stationary part of the road bed which supports the rail 5\ and,overh hich the rail tends to creep under the well known conditions.

My improved anticrecpcr is supported by the rail base 6 and is of thefollowing construction: Extending bcncatu the rail base (i is a memberor bar 7 having a hook or ide jaw formed on one end thereof which ishooked over and which engages one si e of the rail base 6, as shown. Theother end of the bar 7 is provided with an upwardly extending arm 9which is adapted to engage the side of the rail base 6 opposite to theside thereof engaged by the jaw 8 and prevent outward movement of thejaw from the rail base, when the parts arein the position shown in thedrawings.

The arm is provided with an opening 10 into which is inserted theoutwardly projecting arm 11 of a keeper 12 which rests against the innerface of the arm 9 and extends over the adjacent side of-the rail base 6and engages the top thereof andpre vents downward movement of the end ofthe bar 7 carrying the arm 9. The arm 11 of the keeper 12 is providedwith a shoulder 11 which is adapted to engage the adjacent edge of therail base 6 and prevent displacement of the l-zcepcr 133 from the arm 9when the parts are in the position shown in the drawings. When it isdesired to remove the anticrccpcr from the rail, the end of the bar 7carrying the arm 9. is raised so that the shoulder 11 clears the edge ofthe rail base (i. The arm 11 is then withdrawn fron'i' the opening 10,and the end of the bar 7 carrying the arm 9 is then lowered until thearm 9 is below the plane of the bottom of the rail 5. The jaw 8 may thenbe moved outwardly from the rail base. The anticrceper may be appliedtothe rail by a reversal of the operation just described.

The top of the bar 7 is provided with a depression 13 therein in whichis placed a suitable spring 1 1, preferably helical in form, as shown.Normally thev spring 14, rests upon the bottom of the depression 13 andthe upper end of the spring extends above the top of the bar 7 asuthcient distance to cause the spring 14 to be compressed when theanticreeper is applied to the rail. so that, after the anticreeper hasbeen applied to the rail, the spring 14 will force the bar 7 downwardlyand thus force the keeper 12 and the upper part of the jaw 8 down uponthe rail base 6 and serve to firmly hold the anticreeper in gripping endwhich is adapted to engage'the cross-tie 2 and prevent the railfromcreeping. The

abutment portion 16 of the anticreeper is preferably located adjacent toone end of the ar 7 so that the other end of the bar 7 will bemaintained out of contact with the crosstie 2. Should the rail 5 attemptto creep forwardly, the abutment 16 will engage the cross-tie 2 andprevent forward movement of the end of the bar 7 carrying the abutment16, while the rail 5 will carry the other end of the bar 7 forwardly;and, immediately upon the initial creeping movement of the rail 5, thebar 7 will tend to assume a diagonal position beneath the rail 5,forcing the arm 9 and the wall 17 of the jaw 8 inwardly against therespective sides of the rail base 6, thus causing the anticreeper toincrease its grip upon the rail.

I referably provide the wall 17 with outwar ly diverging faces, as shownin Fig. 1, which meet in a central hearing which engages the side 'ofthe rail base 6 to bring the strain within the jaw 8 centrally of thebar 7; and I provide the wall 18 of the arm 9 which engages the side ofthe rail base 6 with similar outwardly diverging faces, as shown in Fig.1, which meet .in a central hearing which engages the side of the railbase to bring the strain centrally of the arm 9 and bar 7 when theanticreeper grips the rail by the action of the bar 7 in tending toassume the diagonal position, as previously explained.

he wall of the depression 13 surrounding the spring 14 preventsdisplacement of the spring from its operative position; and, by thenovel construction hereinbefore described, I am enabled to employ thewell known helical spring commonly used to hold nuts in place inrailroad structures, as the spring means which maintains the anticreeperin gripping engagement with the rail, so that such springs which areused in great numbers and are available in nearly all localities alongthe tracks of railroads may always be at hand for use in connection withmy improved anticreeper.
